The European Union will start talks with Bosnia on Friday on an accord to move the country closer to joining the 25-nation bloc.

The EU Enlargement Commissioner Olli Rehn will travel to Bosnia to open talks on the Stabilization and Association Agreement. EU foreign ministers say Bosnia's progress on the agreement depends on its willingness to continue reforms and cooperate with the U.N. war crimes tribunal.

Two key Bosnian war crimes suspects, Bosnian Serb leader Radovan Karadzic and army commander Ratko Mladic, remain at large.

The EU Monday also extended the mandate for the more than 6,000 peacekeeping troops in Bosnia through next year.

The EU decisions came as senior Bosnian and U.N. diplomats meet in Washington to mark the 10th anniversary of the Dayton Peace Accords, which ended the three-year war in Bosnia-Herzegovina.
